摘要： A method and apparatus for deriving a temporal motion vector predictor (MVP) are disclosed. The MVP is derived for a current block of a current picture in Inter, or Merge, or Skip mode based on co-located reference blocks of a co-located block and a flag is used to indicate the co-located picture. More than one co-located reference blocks can be used to derive the temporal MVP and the co-located reference blocks can be selected from the co-located block as well as neighboring blocks of the co-located block. A search set comprises search motion vectors associated with the co-located reference block(s) is formed. The search motion vector (MV) corresponding to the co-located reference block in the same reference list is searched before the search MV in a different reference list. Various schemes to accommodate implicit method of deriving co-located picture are also disclosed.

摘要： An apparatus and method for deriving a motion vector predictor are disclosed. A search set comprising of multiple (spatial, or temporal) search MVs with priority is determined, wherein the search MVs for multiple neighboring reference block or one or more co-located reference blocks arc configured into multiple search MV groups. In order to improve coding efficiency, embodiments according to the present invention, perform redundancy check every time after a search MV group is searched to determine whether an available search MV found. If an available search MV is found and the available search MV is not the same as a previously derived motion vector predictor (MVP), the available search MV is used as the MVP and the MVP derivation process terminates. Otherwise, the MVP derivation process moves to the next reference block. The search MV group can be configured to include different search MV(s) associated with reference blocks.

摘要： A method and apparatus for deriving a temporal motion vector predictor (MVP) are disclosed. The MVP is derived for a current block of a current picture in Inter, or Merge, or Skip mode based on co-located reference blocks of a co-located block. The co-located reference blocks comprise an above-left reference block of the bottom-right neighboring block of the co-located block. The reference motion vectors associated with the co-located reference blocks are received and used to derive the temporal MVP. Various configurations of co-located reference blocks can be used to practice the present invention. If the MVP cannot be found based on the above-left reference block, search for the MVP can be continued based on other co-located reference blocks. When an MVP is found, the MVP is checked against the previously found MVP. If the MVP is the same as the previously found MVP, the search for MVP continues.

摘要： A method and apparatus for deriving a motion vector predictor (MVP) are disclosed. The MVP is selected from spatial MVP and temporal MVP candidates. The method uses a flag to indicate whether temporal MVP candidates are disabled. If the flag indicates that the temporal MVP candidates are disabled, the MVP is derived from the spatial MVP candidates only. Otherwise, the MVP is derived from the spatial and temporal MVP candidates. The method may further skip spatial redundant MVP removal by comparing MV values. Furthermore, the parsing error robustness scheme determines a forced temporal MVP when a temporal MVP is not available and the temporal MVP candidates are allowed as indicated by the flag. The flag may be incorporated in sequence, picture, slice level, or a combination of these levels.

摘要： An apparatus and method for deriving a motion vector predictor are disclosed. In video coding systems, the spatial and temporal redundancy is exploited using spatial and temporal prediction to reduce the information to be transmitted or stored. Motion vector prediction has been used to further conserve the bitrate associated with motion vector coding. In a conventional coding system, a motion vector predictor (MVP) is selected from the spatial MVPs and temporal MVP. The spatial MVP according to a conventional approach is based on motion vectors (MVs) of neighboring blocking pointing to a target reference picture in a given reference list. Embodiments according to the present invention perform the MVP search among an extended search set including MVs pointing to other reference pictures in the given reference list or the other reference list and MVs pointing to the target reference picture in the given reference list or the other reference list. Other aspects of the present invention address the search order of the search set and configuration of neighboring blocks.

摘要： A method and apparatus derive a motion vector predictor (MVP) for a current block in an Inter, Merge, or Skip mode. Embodiments according to the present invention determine redundant MVP candidates according to a non-MV-value based criterion. The redundant MVP candidates are then removed from the MVP candidate set. In other embodiments according to the present invention, motion IDs are assigned to MVP candidates to follow the trail of motion vectors associated with the MVP candidate. An MVP candidate having a same motion ID as a previous MVP is redundant and can be removed from the MVP candidate set. In yet another embodiment, redundant MVP candidates correspond to one or more of the MVP candidates that cause the second 2N×N or N×2N PU to be merged into a 2N×2N PU are removed from the MVP candidate set.
